Like numerals designate corresponding parts in all of the figures of thedrawing.

Vhile it is comparatively easy to `lubricate a vertical shaft, and thevthrust bearings carried thereby, under the influence of gravity,difficulty has been experienced inl properly lubricating thethrust/bearings of horizontal shafts, becausel the oil tends to move, bygravity, away from the bearings.

' The device of` thepresent invention is sok arranged that the rotationof the shaft in an oil bath picks up the oil and thrusts it, through thewear-plate of the bearing and to the working face thereof. n In thedrawings, 5` designates the shaft, `andvt a fixed bearing element, inwhich said shaft turns, these'features being illustrated in theapplications previously filed by us. y y u sired, be associated with anoil bath in which oil may be maintained up to a desired level fas iscommon inmany mechanical devices.
